I have not asked my T to change anything, nor would I. It's not my office.

I wear layers because she keeps it warm, I have turned down the odd offer for a drink or something and I even pocket my used tissues (I only recently realised she even had a garbage bin when she offered it a couple months ago. But it is not accessible from my seat, so I haven't used it unless she offers it). I hardly even rearrange/fluff the cushions where I sit!

I am acutely aware that it is her space, not mine.
